During POST, each component controller loads its own instance of the required
driver and sets its own configuration using ORCA. The dual controller is
displayed in both Systems Insight Manager and ACU as two separate entities in
one slot. In these utilities, the slot number label for the expansion module has a
lowercase b suffix, while the slot number label for the main controller has no
suffix.
NOTE: When an expansion module is installed, the capacity of the
battery-backed write cache on the main board is divided equally
between the expansion board and the main board. For more
information, refer to customer note CN0316W on the HP website
(

).
